is driven from which are intended 2O 'is a section Fig. 17, to mesh and gear- 36 of lthe lspring motor isl Sound box 41 is adapted to vco-operate with the records '26I the party calling that the vtele, ;raphone is attached and that a message will be recorded. Record or cylinder 42 in a manner similar to the records 26 by means of a .mandrel upon a lshaft' 43 located just above shaft 33 and journalled between the casing and bracket 22. A gear 44. fixed upon one end of shaft 43 meshes with the gearing 45 mounted other end of shaft 43 meshes with a gear 46 fixed upon shaft 33, and drives a gear 47 secured adjacent one end of a feed screw 48, which is rotatably supported in the casing and a suitable bracket 49 Sound box 4() isin communication by means of al sliding telescopic conduit 50 with v ally secured to a crank constructed of a sounding horn 50a adapted to be directed towards the transmitter of the telephone to transmit the message from the record 42, while sound box 41 is in communication through a similar conduit 51 with an orifice 52 centrally disposed in a recess 53 (see Fig. 18) inthe top of the casing and in which recess the receiver 54 is adapted to be placed as clearly shown in Figs. 1, 2 and 22.

The conduits 50 and 5l have projecting frornthe inner cylindrical members thereof the arms 55 and 10 to 14, inclusive) the outer ends of Which are formed into the half nuts 57 and 58 which are adapted to engage with the sere7 v48. slot 59 is provided in the outer conduit members to provide clearance for each arm suliicient to permit the movement ofthe conduits and also to permit sulcient vertical movement of the arms to disengage the half nuts 57 and 58.

`Secured within the recess 53 for the receiver is a switch 60 the poles of which are spring metal and are normally open but which are adaptedto Abe closed by the weight of the receiver 54 when it is placed within recess 53, thereby closing the circuit through the lead wires 61. A pivoted cover 63 is preferably provided for recess 53. Lead wires 61 form one branch of a circuit which is connected across the telephone linel and leads to a small alternatset forth.

spring actuated clamp 65 as shown in Fig. 2l is mounted upon the upper end of a connecting rod 66 for detachably securing said rod to the receiver hook 67 (see Fig. 22) while the lower end of said rod is pivotpin 68 (see Figs. 1 and 5) projecting from a gear 69, a turnbuckle-66a being provided on said rod 66 for adjusting the same. Gear 69 is secured upon one end of a crank shaft 70, suitably journalled in brackets 71, 72, from the top of the casing, and from the motor 63 by worm gearings 73; 74,

is detachably mounted worm gear 84.

56, respectively (see Figs.

o record the threaded shafts 75, 76, and spur gear 77. A one way clutch 78 of the type shown in Fig. 4 is interposed upon sha-ft 76 between the worm gearing 74 and spur gear. 7'7.

A spur gear 79 is and meshes with a pinion 80 mounted upon the shaft of a small spring motor 81. A suitable governor (not shown) is provided within the casing of. spring motor 8l and the main shaft 82 of said motor has secured thereto a worm 83 which is in mesh with a A small pin or lug 85 projects laterally from the face of the worm gear and is adapted to engage a pivoted stop lever 86 upon each revolution of the worm gear 84. Stop lever 86 is normally held by spring 87 in the path of a pin 88 projecting he face of a ratchet `wheel 89. Ratchet wheel 89 is secured to the end of crank shaft 70 and the pin 88 is so located that it will contact with stop lever' 86 when the throw of crank shaft 70 reaches the upper limit of its travel.

The spring motor 81 an-d gears 83, 84 are constructed and arranged tol cause. worm gear 84 to be rotated acomplete revolution in a length of time approximately equal to the time required for the sound box41 to be fed entirely across the record 26 by screw 48, but in order toobviate the necessity for timing the revolution of gear 84 with mathematical accuracy to the time required for the travel of the sound box 4l across the portions of screw 48 are proportioned to the lengths of the records d 42, as shown in Fig. 10, so that even continues to rotate the record 26 and the screw 48 for a greater length of time than required, no further travel of either of the sound boxes beyond their respective records-Will occur. It therefore is desirable to time the spring motor and its connected parts so that the worm gear 84 will'make a complete revolution in a slightly greater time than required for the travel of the sound box completely across a record 26.

A disk 90 secured to shaft projecting therefrom which is adapted to engage a lever 92 `pivotally mounted upon the lower face of spring motor 81 (see Figs. 1, 8 and 9). A spring 93 having its ends secured to lever 92 normally holds the lever against a stop 94 with the right hand end ot' the lever in the path of pin 91 so as to prevent rotation of disk 90 and shaft 82. )Vhcn the alternating current ,motor 63 is rotated,

82 has a pin 91 fixed to crank shaft 70 to drive crank shaft 70 through the gearing and 2) secured to the left bridge across the contacts 97 of circuit branch 62 during the time the throw of crank shaft is travelling from its lowermost position shown in Fig. 6 to its .uppermost position shown in Fig. 7 in which latter position the plate 64' has moved off one of the contacts 97 to break the' circuit from the telephone line to the motor 63. A rod 98 has its upper end connected tothe throw of crank shaft 70 and its lower end is connected to the longer arm of a' bell crank 99 (see Fig. 1), the shorter arm of which is connected by a rod 100- having a lost motion connection 101 therein with the brake lever 39. The lost motion'eonnection 101 (see Fig. 15) lis so constructed that when rod 100 is pushed to the right by upward movement of rod 98 the enlarged head 102 will not engage the head 103 until the throw of counter-shaft 70 has .reached its' uppermost position. This lost .motion movement and the provision of. spring 104 in p.

vided with the elongated slots l127 (see Fig.

connection 101 also permits the brake lever 39 to be'released by the manual actuation of means to be hereinafter described.

Means are provided for automatically rotating shaft 23 with disks 24, 25 to brinr ai fresh record 26 to operative position an said means comprises a rod -105 (Figs. 1 to a pin 106 projecting from thel face ,of ratchet wheel 89, the lower end of said rod being slidably received within a. pivotally mounted tube 107. Intermediate-its ends rod 105 is provided with a pin 108 which is ada )ted toengage, during a portion of its revo u'- tion about the dotted circle shown in Fig.. 2, with one end of th ribs 109 which project laterally from one yside lof a disk 110, secured to shaft 23. he pin 108 and ribs 109 are so arranged as to cause the shaft 23 to be rotated one-sixth of a revolution to bring a fresh record to o'peiative position as will be readily understood. The periphery of disk 110 is provided with ratchet teeth 1.11 with which a spring pressed pawl 112 eugages to prevent backward moven'ient of the shaft Means are provided for automatically reboxes 40 and 41 to their starting positions and said means comprise a plurality of pins 113 projecting laterally from the face of disk.110, opposite to the ribs 109. Each pin 113 as it approaches the top of its travel is adapted to engage a downwardly extending pin 114 (see Figs. 1 and turning the sound seated therein the 1, 6, 7 and 23) of the timing switch which is adapted to pivotallyconnected at its upper vend,

2) projecting from the face of a rack gear 115 rotatably mounted upon a stub shaft 116 (see Fig. 10) secured in the upper face of bracket 21. Engagement of a'pin 113 with pin 114 occurs shoftly after vthe shaft 23 has been rotated a suiiicient distance to move thetop record 26 out of contact with the needle of sound box 4 1.' 'Rackgeai' 115 is in mesh with the rack teeth 117 provided upon an extension of a slide l118. The slide 118 is slidably .supported upon a plurality of brackets 119 which pass through the elongated slots 120 provided in 'said slide and a grooved roller 121 is rotatably mounted upon a stud 122 securedv in a lateral eXtension 21a of 'bracket 21, said roller being in alignment with rack gear rack teeth 117 in mesh with said gear.

Slide 118 is provided with the cut out portions 124 and 125, the lefthand sov 115 to hold the i edges of which are adapted to engage the sound boxes and right when'the sli e the right by pins 113,. 115. A vertically extending portion 126A referably integral with slide 118 is pro-` ush them towards the 118 is pushedtowards 11) through which 11s pushed to the right.

A strong spring 129 (Figs. 1 and 5) has one end anchored to a suitable fixed point and its other end wheel 69 to normally hold the .throw 'of crank shaft 70 in its ower position and, as the signallingcurrent of the telephone is intermittent, a pawl.89 is provided to en gage ratchet wheelf89 and prevent movement of the crank shaft in the direction opposite to the arrow A in Fig. 2. I

j Means are provided to turn the. shaft 23 independently of the spring-motor 344 and for this purpose the shaft 23 is extended through the wall of casing 20 and has secured thereto'a knurled handle 130 (Fig. 1) having a pointer 131 projecting radially therefrom to rotate over a dial 1,32l (see Fig. 23) provided with suitably arranged iudicia to indicate the various operativepositions corresponding to each record 26. As an additional indicating and holding means for the shaft 23 a star wheel 133 (see Figs. 1 and 3) secured upon the shaft 23 inside and adjacent the side of casing 20, said star wheel having a plurality of recesses 134 114 and rack gearv secured to pin 68 lof gear one for each record 26. A lever 135 has a pin136 projecting therefrom which pin is adapted to snap into the recesses 134 with a metallic click under the influence of spring 137 as the shaft 23 is rotated by the handle 130.

Means are provided to assist the brake lever 39 to check the rotation of shaft 23 and said means comprise the brake drum 138 (see Figs. 1 and 5) secured to shaft 23, and with which is adapted to engage the brake band 139 one end of which is sultably secured to the casing and the other end of which has secured thereto one end of an adjustable rod 140, the other end of which is secured to the longer arm of a bell crank lever 141.

crank lever the brake lever 39, the parts being so arranged that when brake lever 39 is actuated The shorter arm of said bell to engage the brake disk 38, rod 140 will pull downwardly upon the brake band 139 to cause it to engage the brake drum 138 and stop the rotation of shaft 23.

' necting rod 145, the

Means are provided to permit the spring motor 34 to be set in operat on independently of the automatic electrical control and thesel means comprise the small bell crank 143 (see Figs. l and 2) pivoted upon the same axis as the brake lever 39, the shorter arm of said bell crank being adapted to engage a pin 144 projecting from the side o f brake lever 39 and the longer arm of the bell crank having secured thereto the lower end of a conupper end of which is connected to a finger grip 146 slidably mounted within a 4flanged ferrule 147 secured to the top of casing 20. Similar ferrules 148 and 149 are provided for the finger grips 150 and 151 which are connected by the rods 152 and 153 to the conduits 51 and 50, respectively, to permit the sound boxes 41 and 40 to be raised manu'ally out of engagement with the records 26 and 42. Each of the finger grips 147, 148 and 149 is provided with a diametrically extending pin 154 the projecting ends of which are adapted to engage within slots 155 in the top edges of the ferrules when the corresponding parts are. lowered and to engage with the top of the ferrules when -the parts are raised.

The sounding horn n changcably fitted into either of the conduits 50 or 51 so as to permit the message which has been delivered to any record 26 to be conveniently listened to when desired. F or checking up what messages may have been delivered in the absence of the subscriber, a memorandum indicator 156 (see Figs. 1 and 5) similar to the parts 130 to 132 is provided.

The operation of the device is as follows: Assuming the parts are in the position shown in Fig. 1 with the throw of countermay ybe interis connected by a rod 142 with b hand end of lever 61. It will be understood the record 42 has been provided with a suitable message.

If the signalling current is now sent through the line, the alternating current motor 63, will be actuated intermittently, thus .causing crank shaft 70 to be rotated y the connecting gearings 73, 7 4 and shafts 75, 76. As crank 'shaft 70 reaches the top of its travel, stop 88 on ratchet wheel 89 (Figs. 1 and 2) will engage lever 86, thus checking rotation of said crank shaft and preventmgspring 129 from pulling the crank shaft downwardly in the direction of the arrow A in Fig. 2 and the engagement of pawl 89l preventing movement of the crank shaft in the opposite direction. Vhen crank shaft 70 reaches the top of its travel thereby releasing brake rotate, thus driving the record 26 and screw 48 through theV gearing provided for that purpose. The rotation of crank shaft 70 with ratchet gear 89 secured thereto, causes pin 108 to engage one of the ribs 109 to rotate shaft 23 and move the top record 26 out of position. Shortly after shaft 23 starts to rotate, a pin 113 engages pin 114, thus causing rack gear 115 to actuate slide 118 and return the sound boxes 40 and 4.1 to their initial starting positions. When crank shaft l'70 reaches its top position the timer contact plate 64 willhave moved to the position shown in Fig. 7 so that the current to the alternating current motor 63 will be shut off and as the stop 88 will bc in engagement with lever 86 the parts will be heldin operative position even if the signalling current continues to ring.

J ust at the moment stop 88 engages lever 86, the lug 95 on gear 79 will cngage'the left 92 and move it to the position shown in Fig.l 9 thus releasing spring motor 81, and actuating gear 84 in the direction of the arrow in Fig. 1. lV-hile gear 84 is. rotating, screw 48 and records 26 and 42 will be rotated, record 42 delivering its message to the transmitter through sound box 40, conduit 50 and Sounding horn 50, while record 26 will receive and record the message delivered by the receiver 54.

As heretofore pointed outspring motor 81 and the'gearsdriven thereby are so timed that gear 84 will make a complete revolution in substantially the same time that is required orysound box 41Ito travel across record 26 and as gear 84 completes its revolution pin 85 thereon will engage lever 86 and move it out of engagement AJwith. stop 88, thus permitting spring 129 to return the `crank shaft 70 to its initial position. As crank shatt 70 is rotated by the alternating current motor 63, it will wind the` spring motor 81 through gears 79 and 80 and as the crank shaft 70 is pulled downwardly by the spring 129 the -one way clutch 78 will permit the rotation of the crank shaft without driving the gears 73, 74 and vmotor 63. When crank shaft 7 0 is pulled downwardy rod 98 Will apply brake lever 39andv brake band 139, thus stoppingthe rotation of the records 26 and screw 48.

Vhen the subscriber returns, the messages which have been received in his absence may be listened tofby raising sound box 40 to the position shown in Fig. 14, turning shaft 23 to any desired record, and releasing brake lever 39 and brake band 139 by means of finger grip 146 to cause spring motor 34 to rotate the record.

Records 26 and 42 arev preferably molded directly upon the mandrel to provide an unitar integral structure consisting of the reclird mandrel and shaft. y
